Research on feasibility and quantity of sediment detention in Lower Yellow River
摘要
Abstract
The water and sediment relationship is an important factor influencing channel erosion and deposition in the hump reach in the Lower Yellow River, while sediment detention is one of the effective measures to adjust the water and sediment relationship. In this paper the necessity of sediment detention in the upstream channel of the hump reach based on analysis of the relationship between water-sediment process in the Lower Yellow River and deposition in the hump reach is demonstrated. Then, by analyzing the characteristics of the river and its recent evolution, the area for sediment detention is determined, which is the Xiaolangdi to Hua-yuankou reach. Considering that sediment detention may bring some risks to flood control and river regime, the bankfull discharge and channel stable condition are taken as the constrain conditions. Finally, the maximum amount of sediment to be detained is 144 million m , which can provides theoretical basis and technical support for river regulation in the hump reach in the Lower Yellow River by sediment detention in the channel.关键词
